IMPROVEMENT IN APPARATUS FOR MOUNTING AND EXHlBlTlNG PICTURES, tic.

Specification forming part of Letters Patent No. 124,953, dated March26, 1872; antedated March 11, 1872.

To all whom it may concern:

Be it known that I, JASON W. HARDIE, of New York, in the county andState of New York, have invented an Improved Apparatus for Mounting andExhibiting Pictures and A1 phabets; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanyin g drawing making part of this specification- Figure 1being a front elevation of the apparatus; Fig. 2, a vertical section ofthe same, cutting from front to back.

Like letters designate corresponding parts in both of the figures.

The nature of my invention consists in an improved arrangement ofendless bands, on which the alphabets or pictures are shown so as toattain the utmost degree of compactness and exhibit several alphabets orsets of pictures in a small space; also, in a very simple, cheap, andeffective device for moving several alphabet or picture-bands,separately or together, by a revolving roller, substantially as hereinspecified.

Let A represent the box or case in which the pictures or alphabets ofletters areexhibited, there being four endless bands of pictures andseven bands, each containing a full alpha bet of letters, shown. Thepictures are arranged in a compartment, B, and the letters in a separatecompartment, 0, of the case. The mechanism of both is the same; and thecase may contain either pictures or alphabets solely, in oneor moresets. First, in' describing the arrangement of the alphabets, as manyendless bands D D are placed side by side as there are alphabets to beshown, so that by them anyword containing no more than that number ofletters can be spelled thereby, and any desired number of bands may beemployed in a case of corresponding width. The endless bands D D arepassed around a series of loose rollers, E E E E E, two of which are infront, one vertically over the other, at a surf ficient distancetherefrom to exhibit on each band a letter on the vertical part of theband, between the rollers; and there is awindow or plate of glass, at,in the front side of the box or case, directly before this part of eachband. Two more of the loose rollers are at the rear of the case, and afifth roller is located near the front rollers, behind and between them,

substantially as represented in Fig. 2, which clearly shows how a longendless band is arranged in'a short space, there being four duplicationsof it in the drawing; and the duplications may be increased in number,if desired, by increasing the number of rollers. These rollers turnfreely on fixed wires or shafts b I) b b b, respectively. There are asmany free and independent loose rollers on each shaft as there are bandsplaced side by side, so that each band moves independent of the others,and all remain stationary till caused to move by the device now to bedescribed. Between two of the duplications of the endless bands issituated a roller, G, parallel with the shafts of the loose rollers E EE E E and out of contact with either duplication, but in close proximityto one-the lower one-asrepresented. This roller is fixed on a shaft, 0,which has hearings in the sides of the box or case, and to oneprojecting end of which is attached a crank, d. Ordinarily, when theroller G is revolved, it has no effect on any of the endless bands. Buta simple deviceis employedfor instantaneously coupling any of the bandsto it, either sepa rately or two or more at the same time, as follows:Directly under the roller G, and immediately under each endless-bandduplication below the said roller, is located a small friction-roller,f, mounted on the inner end of a lever, H, the other end, 9, of whichprojects outward through an opening, h, in the front of the case, farenough to be easily touched and moved by the fingers. The inner end ofeach lever, with its roller, overbalances the outer end thereof, andordinarily rests on the bottom of the case, just out of contact with theendless band above. But by gently depressing the outer end g of thelever the roller f is moved upward against the endless band and pressesthe same against the driving-roller G, which, being then turned, movesthe endless band along as far as desired, so as to bring any letter ofthe alphabet into position behind the glass a. On removing the hand fromthe lever H the inner end thereof immediately falls away from contactwith the endless band and uncouples it from the driving-roller. Thelatter may be roughened or covered with some soft or frictionalmaterial, so as to secure the adhesion of the endless band thereto whenin contact with it. Since simplicity and cheapness are important objectsaimed at in this invention, the levers H H are well. made, of simplestrips of sheet metal, as shown, each having a curved or semicircularbend, Z, near the middle, to form a fulcrum bearing therefor, downthrough a hole in which benda simple tack or small nail, m driven andfitting loosely, keeps the lever in position Without impeding thevibration of the same. The same construction and arrangement of endlessbands, loose rollers, driving roller, and couplinglevers are used forthe pictures, as above described, for the alphabets.

What I claim as my invention, and desire to secure by Letters Patent,is-- 1. The arrangement of the endless bands D D in duplications, sideby side, upon separate loose rollers E E E E E, substantially as and forthe purpose herein specified.

specified.
